Great product but needs to have more sensors
Why did you pick this product vs others?: Works great. The only problem is it will only sound if the bike is moved a couple of feet. It needs more sensors to pick up if anything on the bike is tampered with like lights or if someone tries to get into my saddle bags.

Loud, Reliable, and Effective Anti-Theft Alarm for Bikes and Scooters
I picked up this smart anti-theft alarm for added security on a bike and scooter, and it has been very impressive so far. The alarm itself is compact and easy to mount, but don’t let the size fool you. When it goes off, it is extremely loud. The 115 dB alarm is no joke and is more than enough to draw attention and scare off anyone messing with your bike or scooter. The remote control works well and makes arming and disarming the system quick and simple. Response time is fast, and I haven’t had issues with missed inputs or lag. Having a remote instead of needing an app is actually a big advantage, especially when you just want something that works every time without relying on your phone or Bluetooth. Build quality is solid. The unit feels durable, and the waterproof design gives confidence when leaving it mounted outdoors in rain or bad weather. USB-C charging is another big plus. Battery life has been good, and recharging is easy with the same cable used for most devices. I don’t feel like I’m constantly charging it, even with regular use. Sensitivity is well balanced. It reacts when someone bumps, moves, or tampers with the bike, but it’s not overly sensitive to the point of false alarms from light wind or passing traffic. That balance is important, and this alarm handles it well. Overall, this is a simple, effective security upgrade that adds real peace of mind. It’s loud, reliable, easy to use, and well built. For bikes, motorcycles, e-bikes, or scooters, this is a great extra layer of protection. Five stars and definitely worth having if you want a straightforward anti-theft solution that actually works.

It’s loud !!
I love everything about this, easy installation, small enough to conceal on my new E-bike, and it comes with settings set to high sensitivity. I tried to remove my Bluetooth speaker from cradle as gingerly as possible multiple times and tripped the alarm every time. Great product, I love it !!! 👍

Remote bike alarm
Figuring how to program was a bit harder than the other ones. With the others, they come already set, but this model, the remote has to be paired with the alarm for both to work. But it wasn't too hard to pair. If you want to skip pairing, buy the other model. If you don't mind pairing, then get this model.
